Intraprocedural retrieval of migrated coils during endovascular aneurysm treatment with the Trevo Stentriever device

Retrieval of Migrated Coils with Stent Retrievers: An Animal Study

“…27 Overall, coil retrieval with a stent retriever device appears to be an effective treatment option, regardless of the stent retriever design. 7,[19][20][21] Consistent with our own experience, coil retrieval with a stent retriever is reported to be less challenging and to require less manipulation than coil retrieval with snare devices and the Alligator device. 7 Especially, access to distal or curved vessels with the Alligator device can be very challenging, given its relatively stiff tip.…”

“…5,7,[11][12][13][14][15][16][17][18][19] Coil retrieval with an Alligator device was successful in 1 of 2 reported cases. 14,20 In past years, coil retrieval with stent retrievers, namely the Solitaire, the Trevo, and the Catch system (Balt, Montmorency, France) was reported. 7,20,21 All 18 reported coil retrievals with these devices were successful.…”

“…7,20,21 All 18 reported coil retrievals with these devices were successful. 7,20,21 Coil retrieval with a Merci retriever (Concentric Medical, Mountain View, California) was successful in all 3 reported cases. [22][23][24] Less common techniques involve trapping of a migrated coil between 2 wires, 17,25 manual aspiration, 26 and coil retrieval with an Enterprise self-expanding stent (Codman & Shurtleff).…”

A Case of Retrieval of a Migrated Coil with a Stent Retriever

“…1) As complications during coil embolization, thromboembolism, and intraoperative aneurysmal rupture are commonly observed, 2) but coil migration is also a non-negligible complication that may occur during operation. The incidence of coil migration is reportedly 2%-6%, [3][4][5][6][7] and extensive cerebral infarction may induce serious sequelae; therefore, prompt management is necessary if coil migration occurs. In this study, we report a patient in whom coil migration developed twice during operation, but the two coils were successfully retrieved using a microsnare and stent retriever, and review the literature.…”
